The world building is nice, the art is okay, the MC is your average bland guy (not that there's anything wrong with it if done correctly) with a saviour complex with no motivation whatsoever to drive him and subsequently, the plot forward other than "i want to save them for no particular reason". Honestly the MC doesn't contribute to the plot at all, you could replace him with a supreme brick and the plot wouldn't deviate much. Because reasons stated above, the story lacks a focal point and i just can't seem to get invested in the story.
I think that they should just go all in and make the MC a plot device rather than the focal character and focus the story on literally anyone else, seeing how the status quo changed because of the arrival of the flying castle would be more interesting than this, would rather read a baudrillard book than this, 5/10.
